RAIN-SPOU'I OR CONDUCTING-PIPE.

Specication of Letters Patent.

Application filed November 16, 1912. Serial No. 731,835-

To all whom if may concern.' v

Be 1t known that I, LOUIS GroLAs, citizen of the United States, residing at Washington, in the District of Columbia, haveinvented certain new and useful Improvements in Rain-Spouts or Conducting-Pipes, of which the following is a specification, reference being had therein to the accompanying drawing. j

This invention relates to improvements in rain spouts or conducting pipes and has for its object the overcoming of the damaging results frequently encountered in seamed -metal pipes which are incapable of substantial expansionand consequently burst or 'separate at the seam in cold weather, especially under freezing conditions. Hereto- Yfore, it has been the vpractice to form sheet at the back of the pipe and adjacent to the wall.

My present inventionv comprehends the provision of a pipe provided with an eXpansible Vjoint or seam permitting substantial enlargement of the pipe circumferentially under internal pressures; and the formation and arrangement of said safety joint or seam so that even under unanticipated conditions tending to separate the joint or loosen the interlocked flanges, the internal construction of the pipe will tend to still conduct the water through the pipe rather than tending tocause the escape of the water through any crevice or lopening in the wall thereof.

The preferred embodiment of the invention comprises a spout kor conducting pipe made up of relatively short sections vas compared to the practice in vogue, and the joining of the individual sections together along a diagonal line across the front thereof, the piping at the oint forming an internal bead or ridge across the line of falling movementof the water through the pipe, acting to cause the water to jump or ow across the joint yrather than along the internal groove at the joint as is the case with a seam occupying a true vertical position; also the connecting of the pipe sections together so thatV the diagonal seams thereof will break joint to further overcome anyv tendency of the water in its course of flowing movement to follow the seam from section to section and to prevent elongation of a cracked or opened seam; and the formation of the oint or seam so that the members constituting the joint may relatively separate or contract while maintaining a proper sealed relation there- Patente-a aug. 26,1913. l

between, all as will more fully hereinafter' f appear.

I have illustrated in the accompanying drawings forming a part hereof a convenient `embodiment of the invention, and the details in the construction and arrangement will be apparent from an inspection of the same in connection with the specific description hereinafter contained.

In the drawings: Figure l is a front view of the conducting pipe; Fig. 2 is a similar enlarged view of one of the pipe sections; Fig.` 3 is an inside view of a section showing the seamed portion or joint thereof, Vand Figs. 4 and 5Y are enlarged cross sectional views of Fig. 2.

Referring now more specifically to the drawings wherein like reference characters designate corresponding parts in the several views, A represents a series of short-length pipes of circular cross-section connected together by soldering or otherwise, at the meeting ends thereof, as indicated at B. By

plates the sections of approximately three j feet in length. l Each section is formed with a longitudi- 1 nal joint of an eXpansible character constituted by reversely bending over the edges of lthe sheet metal as at C and D to constitute flanges adapted to interlock, as clearly illustrated in the drawings. It is'not intended that the edges of the flanges or hook-like parts shall abut the closed or base portions c 0l but rather that there shall be a substantial space c d therebetween permitting expansion and contraction of the joint members. Within the base porti-ons of the hook-like edges l may interpose a packing E, preferably asbestos, to better seal the joint, and the purpose of the asbestos material being to resist any burning-out tendency under the heating' of the ends or other portions of the pipe sections in the soldering operation. The joints or seams of the pipe sections are not arranged in a true vertical position but are disposed diagonally across the front of the pipe, my conception embracing the placing of the joint at the front of the pi pe as distinguished from the back thereof as is usual to render the same more accessible in case of needed repair, etc. lf also arrange the diagonal seams of the sect-ions of pipe so that they breakjoint in adjoining sections so that in case of any ripping or pulling apart of one section, the same will not have a tendency to carry on through the adjacent section but will be interrupted by the solid portion of such adw jacent section'bridging the end of the joint of the section connected thereto. rlhe inner edg'e F of each pipe section which underlies and hooks into the outer edge G forms at the fold or bend H an inwardly projecting ridge or raised part with reference to the outer edge, and by reason of this formation, together with the diagonal positioning of the seam, the same crosses the normal path of falling movement of the water through the pipe and causes the latter to jump across the crevice or space at the seam, so that the water will continue its downward vertical course through the pipe, flowing constantly away from the oint, as is not the case where the joint is truly vertical and the water has the tendency to flow down and follow the crevice or groove at the joint. This feature is especially advantageous in instances where under freezing conditions the pipe is unduly expanded and the seam or joint tends to part, which, in a vertical arrangement of the same will permit the water to flow through the wall of the pipe to the outside of the same, whereas in the present instance, the inwardly projecting edge or ridge acts, as previously stated, to cause the water to jump across the seam and follow` its expected course down through the pipe.

From the foregoing construction it will be appreciated that in a simple and cheap manner I have provided a rain spout or conducting pipe well adapted for its intended purposes, and possessing improved characten Aistics, as set forth, over similar piping heretofore disclosed in this art, while enabling` easier assembling of the improved type of,` pipe with standard elbow constructions, and l fittings. i

I am aware that it has heretofore been attempted to provide expanding pipes butt they have been of peculiar shapes 1n cross-i section, and otherwise rendering the same expensive of manufacture and assembling, in that correspondingly special fittings had to be furnished, but it has been the aim of the present improvements to keep as nearly as possible to the standard cylindrical pipe, capable of assemblage and association with other parts as is the prevailing practice.

My pipe sections are easily manufactured, it simply being necessary to either form the hook flanges at the edges of the sheet metal either before or after bending the same into the circular or tubular formation, then hooking the edges together with the elastic packing in place, and then simply twisting the pipe by en gagemcnt of the ends thereof and Aturning' the saine in opposite directions to dispose the seam or joint diagonally or obliquely with reference to the pipe, after which the joint is closed tight on a mandrel to insure its maintenance in the condition thus formed.
